Nominal diameter of API 650 carbon steel tank
Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API 650 carbon steel tank butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.
Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API 650 carbon steel tank is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API 650 carbon steel tank Tanks must be above ground with a closed or open top.
Tunisia cutomer purchased around 1500 tons 304L,310S stainless steel plate from us and make tanks in August, 2017. The company was skilled in the design and manufacture of stainless steel tanks, API 650 carbon steel tank processing systems and equipment for the food, dairy, beverage, chemical, pharmaceutical, biotechnology, and pure water industries. They also sent the inspection team come our company and visited our production line. After using our stainless steel plate, the customer was very satisfied with our products.
}The cost of mechanical cleaning for vertical storage tank, API 650 carbon steel tank is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API 650 carbon steel tank is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API 650 carbon steel tank adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
Both parties shall confirm the API 650 carbon steel tank material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API 650 carbon steel tank steel plant.
